To all whom it may concern. 7

Be it known that I, ERNnsT J. MARTIN, a citizen of the United States,and a resident of New Rochelle, in the county of VVestches ter and Stateof New York, have invented new and useful Improvements in Artist-sFrames, of which the following is a full, clear, and exact description.

This invention relates'to artistsframes,

and was primarily designed for use by scenic artists.

One of the diiticultiesthat often confront scenic artists is how tosupport a flexible paint receiving foundation of large dimensions in aroom of comparatively small-"di-I niensions, thus eliminating thenecessity of providing a building of suiiicient" size to house the paintreceiving foundations of the greatest size that they may be requiredtooperate upon in the carrying on of their work. Once such a problem hasbeen solved it is possible for the scenic artists to carry on work onall sizes of paint receiving foundations without making a large outlayto provide a building of sufficient size to' accommodate all sizes offoundations that he may find it necessary to work upon. The generalobject of'this invention'is the provision of anarti'sts frame for sup:porting flexible paint receiving foundations of dimensions several timesthat of the cross section of the building or room in which it is desiredto work. f'

A further object is the provision of an artists frame capable ofadjustment to -accommodate various sizes of paint receiving foundations;7 g 7. Another object'fis the provision of an artists framewhichsupports the painting face in such a position thatfit slopesaWayfrom the vertical towards the bottom. 'This object is accomplishedbyproviding roller supporting means spaced in triangu- 7 lar relation forsupporting the paint receiving foundation and providing meansinconjunction with the roller'supplorting means for varying the distancebetween any two of the-rollers so as to accommo'daate paintfl receivingfoundations of difl eren't sizes and so locating two of the rollersthata'portion of the paint receiving'fou'ndation is re: tained in apositionfl'slopin'g away from the vertical towards" the bottom. i

These and other objectsof the invention will-be -'moreclearly understoodfrom the following detailed description and accompanying drawings, ofwhich Figure 1' is a side-elevation of the artists frame with. a paintreceiving foundation mounted thereon; I

Figure 2 is frame; Figure 3 is a Figure 4; and j t Figure -4 is asection alongthe line 44', Figure 2. y j

Referring to the above-mentioned draw ings, tWo end supporting posts 10and 11 areshown attached to the ceiling 12 and section along'the line3+8,

floor 13 of any room or building in which the framemay be located, anda'center supporting post 14 carried by means of braces 15, 16, 17 and 18is attached to the endsupporting posts 1.0 and 11. Each of the posts 10,11 and 14, have two brackets 19 and '20 attached thereto Which-areprovidedwvith bearings in which the's'hafts 21 and 22 are mountedrespectively. A curved arm 23 provided with a trunnion 24 is provided inconjunction with? each post and supported on each post by means ofabracket 25 which has a slot 26 cut therein inIPwhich the trunnion 24moves. -Ashaft27 is journaled in these arms. A rod 28 is slidablymounted in guides 29 and 30 mounted on each post, and the upper-end ofeach rod 28 is connected to the curved arm 23 mounted on thecorresponding post! Each rod 28 is operated by means of a connecting rod31 and a bell crank 32" which-is fixed'to a shaft 33 j ournaled in'brackets 34 carried by the posts.- A gear 35 is mounted on the-shaft anend elevation of the'artists 33 and is operated by means of aworm gear36 mounted on the post 10. This Worm gear is operated by means of acrank 37;

In this particular construction, as shown in Figure '4, two rollers 38are] loosely mounted'on each shaft; These rollers are provided withgrooves 39 in which 'belts 4O are located. These belts 40 are rovidedwith projection 41 which'engage t ejpaint receiving" foundation 42mounted upon-the rollers so as to prevent the-(said paint receivingfoundation from slipping thereon;

Provided in the rollers 38 n lQ untedvon the 105.

shaft 21 are chambers 43 and I Located in each chamber and fixedto theshaft are collars-45 "and 46 provided with 'pins 47-. and 48,respectively,"Thesepins .47 and 48"en- V age'in'openings provided in thedisks 5].

supported on the post 10 by means of bracket 54; and-pin 55.

r A U-shaped portion 56 of the lever 53 engages a spoolshaped collar 57fixed to the shaft 21, serving as a means for moving the shaft 21endwise. The pins greater length than-the pins 4 8 and so by themovement of" the shaft either one'or .tworollers may be connected to theshaft so as to drive them upon the operation of the shaft. A groovedwheel 58 'is fined to each end of each shaft 21-, 22 and 27 and a belt59 extends around the wheels. 58 locatedat each endofgthe frame. These-wheels'58 and the belts 59 serve as a means for operatingthe shaft and,through the shafts and connecting devices mounted on the shaft 21 therollers Four plates. are provided with. a plurality of hooks (52 and eyemembers 63.

These olates serve t en ane the on aosit l a i. 3

ends of thelpaint:receiving foundation 4.2,

er a lacing .61, is supplied forfattaching the eye members of thedifferent plates 60 so as to connect the opposite ends of the. paintreceivin foundation 12- in order. to hold the Zh r latter in positionupon the. rollers 38.

In order to give considerable rigidity J to. the center post 14, thebraces-15 and 18 support the post through a cross arm (it which is finedto the post. Turnbuckles are connected into the braces 15 {1018,inclusive, so that. they. maybeadjusted to. bring the center bearings.supported-by the center post 14 into al-inement with the other bearmga Ve In using this frame the rollers 38 carried by. the shaft27 are moved.-to what is decidedto be the proper distance, from the rollers38carriedby the. shaft 21 so that the perimeter. about all the rollerswill be slightly greater than the length of the paint receivingfoundation. The lever 53 isthen operated connecting the, rollers 38 onthe shaft 21 to the shaft. The. paintreceiving foundation is thenengaged with the pro jections. 41 on the belts a0 I and woundabouttherollers. The, hooks of the plates 60 are engaged in thej'oppositeends. Ofthe paint receiving; foundation, and: the eye members areconnected together. by means of the laclZ-his. holds. the paintreceiving foundation in position on the rollers. The

lever. 58,;is: then; eperatede, 'moving the shaft gl asseeninhiguregtftqthe left, engaging the ins. 4;7;.anrl 48 inthe disks. 51and. 52,

' thusconnectingthe rollers to/theshaft.

After this. connecting(operation has been completed" the rollers may.be? operated by operating-the. belt- 59' to move the. paint re:-

. eeiving; foundation; to. any desiredposition.

47' as shown are of After the paint receiving foundation has beenstretched upon therollers the, crank 3? might be operated to move; theshaft 2? outwards so as to tension the paint receiving foundation 42.The operation of the mechanism" for controllingthe position of the shaft27 is as follows: The worm gear 36 is operated by means of the crank 37,rotating the gear, 35 andthrough it the shaft 33. This rotates the arms32 towards a vertical position, forcing the ro1ds28 upward, mov: ing thearms 23 outward thus shaft 27 from the shaft 21.

The shafts 21 and 22 are so positioned with regard to the frame that theportion of the paint receiving foundation extending between them fallsaway from the vertical towards the bottom. The advantage of such aconstruction is that when drops of paint fall from thehrush while thepainting op; eration is carried on there is nodanger of it coming incontact with the paint receiv ing foundation EDI streak the same.

It will be seen fromthe foregoing description that the shaftQl may. beconnected 1: to one, ormore of the rollers mounted thereon. This. allowsthe'frame to be usedfor paint receiving foundations which are small.

A smaller paint receiving foundation extends over. the rollers placed;triangular relation to one another, and by connecting one rollerto. theshaft 21'? all the rollers are driven through the belt means59. Thebelts which are located on. the rollers38 are ad: justahle sons to allowthe shafts 27 and 21 lee to be set with different distances between.

ing. fieXiblepaint; receiving mediums comprising. supporting. members,three. lines of rollers. spaced in triangular. relation. to one anothercarriedby: the supporting. members,

one line of said-rollers being-. mounted.on

arc-shaped plates carried-by the supporting members, and means. foradjusting said are?- shaped plates-to increase the distance be.- tweentwo. of the lines of rollers toaccoinmodate different sizedpaintreceivingmediums.
